The Integra K-701 was ONKYO’s flagship cassette deck in the July 1988 catalog. Its three-head design with a PCOCC head and silent transport mechanism enabled simultaneous record and playback monitoring. Dolby HX-Pro dynamically adjusted bias current to the signal level, extending the high-frequency recording range across all tape types. A four-digit real-time counter displayed remaining tape time even during fast-forward or rewind.
